CHARLES E. SEE, OF CHARLEVOIX, MICHIGAN.

LADDER.

SPECIFICATION forming part of Letters Patent N o. 708,670, dated September 9, 1902. Application filed January 18, 1902. Serial No. 90,244. (No model.)

To all whom, it may oon/cern:

Be it known that I, CHARLES E. SEE, a citizen ofthe United States, and a resident of Charlevoix, in the county of Charlevoix and State of Michigan, have made a certain new and useful Invention in Ladders; and Ideclare the following to be a full, clear, and eX- act description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to theaccompanyingdrawings, and to letters of reference marked thereon, which form apart of this specification.

Figure l is a side elevation of my ladder as applied. Fig. 2 is a section on the line 2 2, Fig. l. Fig. 3 is a detail view of one of the steps m.

This invention has relation to adjustable collapsing stairs for the upper berths of vessels and cars and other purposes to which it may be suited; and it 4consists in the novel construction and combinations of parts as hereinafter set forth.

The object of the invention is to provide for conveniently getting into the upper berth means which will nevertheless be readily moved out of the way of access to the lower berth, and yet will be securely connected to the berth, and of strong` and compact structure.

In the accompanying drawings the letter ct designates the upper berth, and b the lower berth. Y

c represents a bar or rod extending along or below the side rail of the upper berth, usually from the foot of such berth to a little beyond its middle portion. This rod or bar is secured to such side rail of the berth, and at its foot end is fastened,by means ofa threaded socket, either to the side rail of the berth or to the wall of the room, a swinging-hook d.

e designates the stairs or folding steps, which consist of one pair of inner side bars or stringers ff and another pair of outer side bars or stringers g g. The pair of inner stringers ffare securely connected by means of the pivot-bearings at end of steps and at their upper ends are provided with strapnected bymeans of the'piVot-bearings, 'and the Stringer nearest the foot of the berth is provided with a perforation Zfor purpose of engagement with the aforesaid catch or hook cl.v The inner sides of the stringers are bored or provided with pivotal bearings for the pivots p of the steps or stairs m, which are made quite broad, so as to be stable and secure under the foot notwithstanding theremay be considerable motion or vibration ofthe car or boat at the time of use. The perforation Z of the outer stringeris placed even with reference to the top of the inner Stringer when raised, yso that when the pair of outer stringers is raised or collapsed against the pair of inner stringers such perforation will be in position to engage the hook d, which serves the double purpose of holding the steps in folded position, so that they take up but little room, and at the same time holds them at the foot of the berth out of the way. Usually the inner or rear' stringers are made alittle shorterIthan the outer pair,so that their lower ends will not touch the floor, or they may have small casterson their' ends.' outer pair of stringers islet down, their lower ends rest securely upon the door of the room,

and the broad steps afford a means for ascending into the upper berth in a more comfortable, secu re, and convenient manner than is the case with the ordinary step-ladder.

Having thus described my invention,vwhat I claim as new, and desire to secure by Letters Patent, is-

l. `The combination with the foldable stringers, and the broad steps pivoted thereto, of the berth track-bar, the runner connections of the inner stringers,'and means for holding the outer stringers in folded position and infixed relation to the end of the berth, substantially as specified.

2. The combination with a berth track-bar, and adjustable collapsing stairs having'runner connections with said track-bar, of means for holding the stairs in collapsed or folded When theV position and in fixed relation to the track said outer pair of stringersinraised position, bal', substantially as specified. substantially as specied. 1o
